I started using a CPAP machine on 12/8/21 and while I am sleeping much better I've noticed within the last few weeks or so that I'm experiencing shortness of breath, rapid weight gain and swelling around my lower legs and ankles. I used to get up between 2 and 5 or more times a night before using the machine and now it's only once on most nights. I've had some cardio issues in the past and I've scheduled an appointment with my doctor for tomorrow.
